Mouse cursor motion problem in Mac

I've worked on all sorts of Macs and I've never had a problem with the mouse motion (except with the old puck mice, but that was a mouse hardware design issue).

I've always found it smooth and similar to windows (at work I have a mac and a PC at my desk and notice no difference going between them).

I'm assuming you fine tuned the settings in OSX? Also, since your using a mouse with your laptop, did you turn the trackpad off so nothing is resting against it (like a palm or stray finger)?

 

You are probably talking about the difference between the way an OS-X mouse and a Windows mouse work--they are different--so it is understandable that you notice it. There are a ton of posts here on mouse movement--just search and you will see what I mean.
